DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1700Z July 13, 2009

Oklahoma/W Texas:
Remnant smoke from the fires in Oklahoma over the past couple of days
was seen this morning along much of the Texas/Oklahoma border along the
Red River. The smoke also covered much of western Oklahoma, excluding
the Panhandle, and extended to the southwest to the Big Bend area of
west Texas. The smoke was mainly thin.

New Mexico:
Remnant thin smoke from yesterdays fires in Arizona and New Mexico was
observed in two patches across north central and east central New Mexico.


Northern California to Idaho:
A narrow area of light aerosol was seen this morning extending from just
south of the San Francisco Bay area to the northeast across central
and northeast Nevada into eastern Idaho. It is difficult to determine
the source or composition of the plume but based on afternoon data
from the Ozone Monitoring Instrument (OMI), which detects SO2, and
weather trajectories for the past few days, it is felt that the plume
is predominantly smoke from the ongoing fires in Alaska.

British Columbia to Great Lakes:
An extensive area of aerosol was seen stretching from central Saskatchewan
to the southeast across southern Lake Winnipeg and then along the
northern Minnesota border across the western portion of the upper
peninsula of Michigan and into central lower Michigan. Based on the
OMI data noted above, it is felt that this plume is predominantly SO2,
although it is possible that some smoke is mixed in. OMI data can be
viewed at http://satepsanone.nesdis.noaa.gov/pub/OMI/OMISO2/index.html

Alaska:
Remnant and recent smoke from the Alaskan fires was seen drifting to
the northwest and covering much of the northwest portion of the state,
mainly north of McGrath. The smoke was most dense roughly between Mt
McKinley and Huslia.

Eastern Canadian Maritimes:
Two broad areas of remnant smoke were seen over the open waters of the
north Atlantic and the Labrador Sea east of Newfoundland. An area of
moderately dense to dense smoke was lifting north through the Labrador
Sea toward the Davis Straight. A second area of lighter density smoke
was seen extending from east of St John's Newfoundland northward to an
area southwest of the southern tip of Greenland. All of this smoke has
originated from large wildfires burning near Happy Valley Goose Bay on
mainland Newfoundland the past few days.

can be found at the locations listed below.

THE FORMAT OF THIS TEXT PRODUCT IS BEING MODIFIED. IT WILL NO LONGER
DESCRIBE THE VARIOUS PLUMES THAT ARE ASSOCIATED WITH ACTIVE FIRES. THESE
PLUMES ARE DEPICTED IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

JPEG:   http://www.ssd.noaa.gov/PS/FIRE/hms.html
GIS:    http://www.firedetect.noaa.gov/viewer.htm
KML:    http://www.ssd.noaa.gov/PS/FIRE/kml.html

THIS TEXT PRODUCT WILL CONTINUE TO DESCRIBE SIGNIFICANT AREAS OF SMOKE
WHICH HAVE BECOME DETACHED FROM AND DRIFTED SOME DISTANCE AWAY FROM THE
SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. IT WILL ALSO
STILL INCLUDE DESCRIPTIONS OF BLOWING DUST.

ANY QUESTIONS OR COMMENTS REGARDING THESE CHANGES OR THE SMOKE TEXT
PRODUCT IN GENERAL SHOULD BE SENT TO SSDFireTeam@noaa.gov






 


Unless otherwise indicated:
  • Areas of smoke are analyzed using GOES-EAST and GOES-WEST Visible satellite imagery.
  • Only a general description of areas of smoke or significant smoke plumes will be analyzed.
  • A quantitative assessment of the density/amount of particulate or the vertical distribution is not included.
  • Widespread cloudiness may prevent the detection of smoke even from significant fires.
